[Internal]: Multi-selection for Variable controls #3315
Description
Description
We are adding multi-selection support for variable controls elastic/kibana#237228
We need to add this new option to the Variable controls doc https://www.elastic.co/docs/explore-analyze/dashboards/add-controls#add-esql-control and explain to user how they can make it work
elastic/kibana#236404
Proposal:
"You can allow multiple selection in a variable control, however, it will only work if the query of your visualization has the MV_CONTAINS function
Example:
Variable control query (?variable): FROM logs-* | WHERE @timestamp <=?_tend and @timestamp >?_tstart | STATS BY host
Visualization ES|QL query: FROM logs-* | WHERE MV_CONTAINS(?variable, host)
